Default Intercooler

I stumbled across a turbocharger intercooler and said, "What the heck" and bought it for $5.
Plan is to stick it diagonally in the window so the ports
fall inside and outside the plane of the window. Been trying
to figger out how to make the air pass thru multiple times
to create something more like a cross-flow exchanger.
But it's so massive that it might not make much difference.

If I can figure out which car it fits, I might be better off selling
it and buying a real HRV.

Ideas?

Sell it man, use money for a better heat exchanger. I say this as a person that could use an intercooler.

Hi there, new guy here, great thread, lots of great stuff, anyone working on anything at this time??
I've just acquired a number or sheets of 4mm corrugated plastic (sign material) and am about to start hacking it up and stacking an HX... I see that the cross-flow approach is really simple to build, and I also see a lot of reference to counter-flow... (as in two cross-flow HXs "configured in a counter-flow configuration" I'm having a hard time understanding how 2x cross-flow = counter-flow... but that's anothe thing...) so I 'm wondering how others might have approached configuring sign material in a manner that the opposing air streams are in true counter flow configuration as opposed to 90* angle to each other... Descriptions would be nice, but I'm a visual person so a diagram or picture is worth a million words for me... Any help would be appreciated!

Hey, I have a substantial stack (1' x 1' x 1.5') of pre-cut pieces that you can have for free... I used them for experiments (which worked just fine) and have decided to use a different approach.

Washougal is close to Portland, right?

Do you want them?

It was a pleasure meeting you today AC! Thanks again for the HX material! I'll keep the group posted on how it's put to use.

We'll need to get together again soon and conspire to save some energy! (Let me know if you got my email)

geodans, great to meet you, too.

I'm glad to be able to help you on your HRV project.

Your new home build sounded pretty spectacular from a EcoRenovator point of view. I don't know if you did much in the way of progress photos, as you went along, but if you did I, think they belong on a new thread. You may have established a new high water mark.

Yes, I did get your email...

Keep in touch.

Best,

-AC

Hey Fornax,

Any news about your hrv? Did you get those heat exchangers from recair?
